The New Orleans Saints' first-string offense had an impressive workout against the Houston Texans on Thursday, with one glaring exception - an interception thrown by quarterback Drew Brees to former Saints linebacker Danny Clark in team drills. It wasn't even clear whom the intended receiver was. Brees threw the ball directly at Clark in the middle of the field.

Other than that hiccup, though, the Saints' passing offense looked sharp. Brees hit receiver Marques Colston down the left sideline for a long gain. He hit tailback Pierre Thomas with a nicely-timed screen pass that went for a long gain behind a series of blocks. And he fired a beautiful 16-yard touchdown pass to tight end David Thomas over linebacker Zac Diles during red-zone drills.

The Saints' first-string defense was solid on the other side of the practice field. They held tight inside the 10-yard line during one set of team drills before the Texans appeared to score on fourth down. And backup linebacker Marvin Mitchell reeled in an interception from backup quarterback Dan Orlovsky that he likely would have returned for a touchdown even if they were live tackling.
